Mesmerist's Misdirection

[Alayern]

Misdirection Mesmerist Trick Description:

-An enemy's perception of an attack by the subject shifts, making the foe unprepared to defend against the attack. The mesmerist can trigger this trick when the subject makes an attack or uses a spell that requires an attack roll. The mesmerist attempts a Bluff check to feint against a single target of the subject's attack. Unlike a normal feint, this ability can be used on non-melee attacks. If the feint succeeds, the target of the attack is denied its Dexterity bonus to AC against the triggering attack. The target doesn't suffer any additional effects that the mesmerist or the subject would cause on a normal feint or Bluff check. This is an illusion (glamer) effect-

If I were a mesmerist with a rogue ally *such intrigue, much conniving, wow* would the rogue get sneak attack damage when I use this trick?

The problem phrase here is "The target doesn't suffer any additional effects that the mesmerist or the subject would cause on a normal feint or Bluff check."

Sneak Attack (for this example) results as a product of a target being denied its Dex. Does it trigger at that stage in the action, or could it be considered an aforementioned "additional effect"?

It's weird, but as written, yes it seems to me that the 'any additional effects' clause would apply to sneak attack. The magical feint caused by this power ONLY removes the Dex bonus to AC. Otherwise, the attack is resolved as if they had not been feinted / still had their Dex bonus.

Sneak attack would definitely work.

It specifically says "additional effects that the mesmerist or subject would cause on a normal Feint or bluff check". So no damage from blistering feint or alternate feint effects like witty feint.

Sneak Attack is not an additional effect caused by feint though. It's an effect that triggers when you are denied your dexterity bonus, which Misdirection explicitly does.
